5 the side walls 2 and 5 to a point of supply, The advantage of the construction is in Ml its compact unitary nature providing a complete self-generating steam cooker.

The trays 16 may be inserted and withdrawn individually; the height of the supports may be varied according to requirements, and the heat is generated and maintained with great economy and regularity, due to the control and regulation of the fuel and water supply.

The main body portions may be made of sheet or plate metal, of durable economical construction, and mounted upon any suitable supportin base as the legs 28 for elevation above the floor. 1 a

The door 20 makes a tight fitting connection with the frame, and any water of condensation drips across sill 29 into a trough 30 having a drain cock 31 for release of any accumulated moisturez By means of the door as thus constructed, the apparatus is capable of tight closure, avoiding any escape of odor, and is otherwise extremely convenient and practicable in construction and operation.

It may, of course, be made in various sizes to adapt it to diiferent requirements of use, and is readily available for continued or limited operation as desired.

Having described my invention, What I claim is a 1. A steam cooker consisting of an outer casing having an uppermost outlet flue and a lower heat generating compartment, a heater in said compartment, an inner casing spaced inwardly from the sides, back and top of the outer casing providing a surrounding gas circulation conduit and terminating at the front in the plane of the outer, casing, said inner casing having at its base a water containing bath, a front door framing and inner transverse supports above the bath, an outer water supply tank fixedly mounted on the side of the outer casing and connected with the bath, means for supplying water to the tank provided with water supply regulating mechanism, a front opening and closing door in the door framing, and means for collecting drip water from the door.

2. A. steam cooker consisting of an outer casing having an uppermost outlet flue and a lower heat generating compartment, a heater in said. compartment, an inner casing spaced inwardly from the sides, back and top of the outer casing'providing a surrounding gas -circulation conduit and terminating at the front in the plane of the outer casing, said inner casing having at its base a water containing bath, a front door framing and inner transverse supports above the bath, an opening and closing door in the framing, means for collecting drip water from the door, a water supply tank fixedly mounted at one side of the outer casing having a feed pipe leading through the outer and inner casing across the circulation conduit and into the bath, and a rounding gas circulation conduit and terminating at the front in the .plane of the outer casing, said inner casing having at its base a water bath, a front door framing and inner transverse supports above the bath, a vapor outlet conduit extending from the top of the inner casing through the gas circulation conduit and the top of the outer casing, an opening and closing door in the framing, means for collecting drip water from the door, a water supply tank fixedly mounted at one side of the outer casing having a feed pipe leading through the outer and inner casing across the circulation conduit and into the bath, and a valve controlled water supply pipe leading to the tank pro vided with a float 4:. The combination with an outer rec-=- tangular casing having an uppermost out-= let flue and a lowermost combustion chain-- ber, of a cooking compartment enclosed within an inner casing spaced from the sides, back and top of the outer casing providinga gas circulation conduit and terminating at the front in the plane ofv the outer casing, said inner casing having a lower water containing basin above the combustion chamber, a front wall provided with a door opening into the cooking compartment and an outer moisture collector, a door for said opening, a water supply tank fixedly mounted at one side of the outer casing having a supply pipe leading to the lower portion of the water basin through the outer and inner casing across the gas circulation conduit, and a supply pipe for the tank having afloat controlled inlet valve.

' 5, 1s a steam cooker provided with an outer and an inner casing providing a lower combustion chamber and continuous gas circulation spaces between the sides, back and top walls of said casings, with a water basin in the lower portion of the inner casing above the combustion chamber and means for furnishing a regulated supply of water thereto, a front wall connected with both of said casings provided with a door opening leading into the inner casing above the water basin, a door therefor, and a drip trough located across the face of the front wall below the door opening.

6.. In a steam cooker provided with an outer and an inner casing. providing a lower combustion chamber and continuous gas circulation spaces between the sides, back and top walls of said casings, with a water basin in the lower portion of the inner casing above the combustion chamber and means for furnishing a regulated supply of water thereto, a front wall connected with both of said casings provided with a door opening leading into the inner casing above the water basin, a door therefor, and a drip trough located across the face wall below the door opening, per projecting sill and a release drain cock.
